Review, Journal: Olanzapine and Samidorphan Combination Treatment: A Systematic Review. (Pubmed Central) - Mar 8, 2022 OLZ/SAM-treatment is associated with mitigated weight-gain liability when compared to OLZ-monotherapy in adults with schizophrenia. Additional studies are needed to ascertain patient acceptability, appropriate selection and sequencing of OLZ/SAM in the treatment algorithms for adults with schizophrenia (and BD-I), as well as to determine cost-effectiveness and long-term metabolic effects.

Clinical, PK/PD data, Journal: Population Pharmacokinetics of Olanzapine and Samidorphan When Administered in Combination in Healthy Subjects and Patients With Schizophrenia. (Pubmed Central) - Feb 17, 2022 Consistent with the known metabolic pathways for olanzapine (primarily via uridine 5'-diphospho-glucuronosyltransferase [UGT]-mediated direct glucuronidation and cytochrome P450 [CYP]-mediated oxidation) and for samidorphan (predominately mediated by CYP3A4), coadministration of OLZ/SAM with rifampin, a strong inducer of CYP3A4 and an inducer of UGT enzymes, significantly decreased the systemic exposure of both olanzapine and samidorphan. Severe renal impairment or moderate hepatic impairment resulted in modest increase in olanzapine and samidorphan exposure.

PK/PD data, Journal: Using Physiologically Based Pharmacokinetic Modeling for Predicting the Effects of Hepatic Impairment on the Pharmacokinetics of Olanzapine and Samidorphan Given as a Combination Tablet. (Pubmed Central) - Feb 1, 2022 In applying the optimized model, mild, moderate, and severe hepatic impairment were predicted to increase steady-state total exposures by 1.1-, 1.5-, and 1.6-fold, respectively, for olanzapine, and by 1.2-, 1.9-, and 2.3-fold, respectively, for samidorphan. PBPK modeling allowed for prediction of untested clinical scenarios of varying degrees of hepatic impairment in lieu of additional clinical studies.

Review, Journal: Olanzapine/Samidorphan: First Approval. (Pubmed Central) - Dec 22, 2021 Olanzapine/samidorphan (LYBALVI) was recently approved in the USA for the treatment of schizophrenia and bipolar I disorder. This article summarizes the milestones in the development of samidorphan leading to this first approval of olanzapine/samidorphan.

Review, Journal: New Antipsychotic Medications in the Last Decade. (Pubmed Central) - Dec 16, 2021 We identified 11 significant developments: the introduction of new antipsychotics cariprazine, brexpiprazole, lumateperone, and pimavanserin; introduction of new delivery subcutaneous long-acting risperidone, aripiprazole lauroxil, transdermal asenapine, and inhaled loxapine; and the introduction of new approaches such as olanzapine/samidorphan for olanzapine-associated weight gain, examination of the TAAR1 agonist SEP 363,856 as a test of concept, and the combination of Xanomeline/Trospium, an M and M muscarinic receptor agonist in conjunction with a peripheral anticholinergic. Last decade has seen a tremendous development in second-generation antipsychotics which provides unprecedented treatment options for clinicians in treating psychosis.

Clinical, Review, Journal: An Evidence-Based Review of OLZ/SAM for Treatment of Adults with Schizophrenia or Bipolar I Disorder. (Pubmed Central) - Sep 18, 2021 As OLZ/SAM contains the opioid antagonist samidorphan, it is contraindicated in patients using opioids and in those undergoing acute opioid withdrawal. Clinical trial results from more than 1600 subjects support the use of OLZ/SAM as a new treatment option for patients with schizophrenia or BD-I.

Clinical, P1 data, Journal: Combination of olanzapine and samidorphan has no clinically relevant effects on ECG parameters, including the QTc interval: Results from a phase 1 QT/QTc study. (Pubmed Central) - Apr 29, 2021 Weight, waist circumference, metabolic laboratory parameters, and schizophrenia symptoms remained stable throughout the study. This thorough QT study in patients with stable schizophrenia demonstrated that OLZ/SAM, in doses and plasma concentrations up to supratherapeutic levels, does not have a clinically relevant effect on ECG parameters, including QT/QTc prolongation.

[VIRTUAL] Olanzapine/Samidorphan Mitigates Weight Gain Across Subgroups of Patients Known to Be at Increased Risk for Weight Gain With Olanzapine Treatment () - Apr 13, 2021 - Abstract #ASCP2021ASCP_155; Baseline demographics were similar across treatment groups. OLZ/SAM was associated with a lower percent change in weight vs olanzapine at week 24 across all subgroups evaluated, with least squares mean differences (95% CI) of −2.38% (−3.88%, −0.88%) in the overall population, −2.73% (−4.45%, −1.01%) for males (n=391), −1.53% (−4.43%, 1.38%) for females (n=147), −3.43% (−7.00%, 0.13%) for age <30 years (n=98), −2.14% (−3.78%, −0.51%) for age ≥30 years (n=440), −2.37% (−4.10%, -0.63%) for black patients (n=392), −2.41% (−5.28%, 0.46%) for non-black patients (n=146), −2.17% (−4.10%, −0.24%) with BMI <27 kg/m2 (n=327), and −2.70% (−5.01%, −0.39%) with BMI ≥27 kg/m2 (n=211).
